Western region (Chaco) · 18k people · 82,349 km²
Alto Paraguay. The empty north.
Alto Paraguay is the least-populated department in Paraguay — 18,000 people on a land area larger than Portugal. The Paraguayan Pantanal occupies the eastern flank along the Paraguay River; the central + western districts are deep dry Chaco with indigenous Ayoreo reserves and almost no roads. Fuerte Olimpo, the capital, has 4,000 people and a small port. For 99% of relocators, this is not a viable destination; for the 1% with a specific reason (research, conservation, large-scale ranching), the cost basis is unbeatable.

01 / overview
What Alto Paraguay is
Three zones. The Pantanal east — wetlands, gallery forest, jaguars, anaconda, tied to the Paraguay River. The dry interior — sparse Ayoreo + Yshyr indigenous communities, scrub, salt pans. The remote west — empty Chaco abutting Bolivia. The riverports (Bahía Negra, Fuerte Olimpo) are reached either by boat (the weekly Aquidabán cargo + passenger boat from Concepción) or by light aircraft.
